The girl who played with fire - Denise Mina

In this graphic novel adaptation of Stieg Larrson's THE GIRL WHO PLAYED WITH FIRE, Mikael
Blomkvist, crusading publisher of the magazine Millennium, has decided
to run a story that will expose an extensive sex trafficking operation.
On the eve of its publication, the two reporters responsible for the
article are murdered, and the fingerprints found on the murder weapon
belong to his friend, the troubled genius hacker Lisbeth Salander.
Blomkvist, convinced of Salander's innocence, plunges into an
investigation. Meanwhile, Salander herself is drawn into a murderous
game of cat and mouse, which forces her to face her dark past.
